TEAS 7 Math Practice Test

Correct Answer: D

Rationale: To calculate the sale price Gordon paid, we first find the discount amount by multiplying the original price by the discount percentage: $472 * 0.30 = $141.60. The sale price is the original price minus the discount amount: $472 - $141.60 = $330.40. Therefore, the correct answer is D. Choice A is incorrect because it only represents the discount amount, not the final sale price. Choice B is incorrect as it does not account for the discount. Choice C is incorrect as it is higher than the correct sale price.

Correct Answer: A

Rationale: The correct answer is A: Shifts = (2)(5) + 4. 1. Nurse Cameron worked 5 shifts in week 1. 2. In week 2, she worked twice as many shifts as in week 1, which is 2 * 5 = 10 shifts. 3. In week 3, she added 4 shifts to the number of shifts worked in week 2, which is 10 + 4 = 14 shifts. 4. Therefore, the equation describing the number of shifts Nurse Cameron worked in week 3 is (2)(5) + 4 = 10 + 4 = 14 shifts. Summary of incorrect choices: B: Shifts = (4)(5) + 2 - Incorrect because it does not account for the doubling of shifts in week 2 and the addition of 4 shifts in week 3. C: Shifts = 5 + 2 + 4 - Incorrect as it

Correct Answer: B

Rationale: To simplify the expression, we follow the order of operations (PEMDAS). Step 1: 7 + 16 = 23 Step 2: 6 * 3 = 18, then (5 + 18) = 23 Step 3: Now, the expression becomes 23 - 23 - 10 * 2 Step 4: 23 - 23 = 0, and 10 * 2 = 20 Step 5: Finally, 0 - 20 = -20 Therefore, the correct answer is B (-20). Explanation for other choices: A: -42 - Incorrect because it doesn't follow the correct order of operations. C: 23 - Incorrect, as it doesn't account for all the operations in the expression. D: 20 - Incorrect, as it doesn't consider the subtraction and multiplication operations properly.
